Quartz sight glass has a high degree of Chemistry
Quartz sight glass has high chemical and thermal, in addition, not only at room temperature, and corrosion resistance of various acid, aqua regia, neutral salt, sulfur and carbon at high temperature and chemical resistance than Ni Cr alloy and ceramic 150 times, good acid resistant materials.
Quartz sight glass is acidic. It is relatively poor in alkali resistance and alkali resistant salt. It can produce soluble silicate with this type of reagent, so it is not suitable for producing strong alkaline reaction apparatus. At room temperature, quartz glass is water. Even at high temperature and high pressure, the erosion of water to quartz sight glass is very small. At 3 atmospheric pressures and 3 hours at 310 C, the weight loss of silica glass is only 1.13 g / M 2.
